acrn-config: Add functionality to find unused vbar base

Allocate unused vbar for SOS and pre-launched VMs.

- For SOS, find unused vbar in the range which is assigned to pci host
bridge. The allocated vbar cannot have confilicts with any existing pci devices
- For pre-launched VMs, find unused vbar in the range 0x80000000 to
0xfffffff. The alloacted vbar cannot have confilicts with any
passthrough devices and mmio.
